About this 3D model
I redesigned the original Jerooney's version of the tumb stick raisers because, in my experience, they are a little bit weak and tends to break. I enlarged the arms that embrace the original stick to give more stiffness to the assembly. for the same reason, I suggest to print the components in PLA-CF. If you have problems with the threads, you can try to print the sticks upside down. Cover the sticks with rubber hoods to have more grip.
